C. A. HABENICHT LOCK Filed May 29, 1922 mmm Patented June 19, 1923.

UNITED STATES CHARLES A. HABENICHT,

.lipplieaa'mn` filed May 29,

and State of California, have invented a new and useful Lock, of which the following is a specification.

The present invention relates to improvements in locks for doors or'the like and has particular reference to a combined latch and lock. One of the principal features of my device is its adaptability to various purposes as Well as the ease with which it may be assembled and taken apart. A- further feature of the invention is the simplicity of construction, its ruggedness and the impossibility of tampering with the lock from the outside of the door.

With these objects in mind I have illustrated the preferred form of my invention in the accompanying drawing vin which Figure l shows an outside elevation of my de,- vice; Figure 2 a section along line 2 2 of Figure 1; Figure 3 a. section valong line 3-3 of Figure 1; Figure 4 a cross-section along, line 4 4 of Figure 3; Figure 5 a cross section along line 5--5 of Figure 3; Figure 6 an elevation looking at it from the outside of the door; Figure 7 a cross section along line 7-7 of Figure 3v and Figure 8 a detail4 view of a key adapted tobe used for the lock. While I have shown only the preferred form of my invention I wish to have it understood that various changes ormodi-v iications may be made within the scope of the claims hereto attached without departin/Ifrom` thespirit oi the invention.

y combination llatch and lock comprises as its principal portions a cylindrical housing (1), a plugV (2) therein having the latch and the lock associated therewith and the keeper (3) adapted to be secured to the frame enclosing the door.

The housing (1) is inserted into the door as shown in Figure 3 so as to extend a limited distance beyond the door on the inside as well as the outside. Itis provided with a circumferential flange (4) which lies against the inside surface of the door and is secured to the same by means of suitable screws (6). It will be noticed that the flange surrounds PATENT OFFICE.

only k.about one-halfof-the housing as indicated iny dotted lines in Figure 1. A collar (7) isv placed around the housing on the outside of the door for finishing purposes.

The plug consists of an inner portion (8) and an outer portion (9)'. v'Ihe outer portion carries the lock. This lock has ,been described in the co-pending application, Serial No.' 458,238, and does not offer any novel features.' It maybe briefly described as comprising ajpluralityv of tumblers (11) pivotally mounted on al pin (12) and provided on their upper surfaces with notches (13) which latter are normally kept out of alignment by the springs (14) but are adapted to be aligned with each other by the use of the key (16). When the notches register they allow a dog (17) pivotally mountedv on a pin (18)"whi'ch is normally forcedinto a, recess (19') inthe housing to drop downward so as to clear the saidfrecess and then allow theplug to be revolved relatively to the housing. f

The inner portion (8) of the plug carries the latch (21). The latter consists of a threaded base (22) and a stem The base is adapted to'be inserted through a cylindrical hole (24) in the lhousing' so as to engage the threaded recess (26) in the'plug volve with the plug through a certain dis-` tance, preferably a quarter of a turn. The

inner plug projects bevond the inner end of .i

the housing as shown -at (29) and receives the nut (31) which prevents `outward motion of the plug relative tothe housing and forms the center of a bell (32) the edge (33) of which bears against the latch stem (23) so as to brace the same. 1 i

A spring (35) secured to the inside of the bell and wound on the housing in several turns presses down on the latch stem so as to normally hold the same in an operative position.

The two portions (8) and (9) of the plug engage each other as shown in Figure 5,that is, two pins '(36) rising from one of the engaging surfaces extend into peripheral recesses (37) of the other portion of the plug'.

The recesses are suiiciently long to allowA oneportion of the plug to turn a short distance without affecting the other one so that the bell may be turned from the inside and open the latch without necessitating` a turning of the outer portion of the plug while on the other handV a turning of the outer portion by means of the key immediately engages the inner portion and actuates the latch. l

The particular keeper preferably employed in connection with my latch comprises a case (38) the two flanges (39) of which are secured to the frame enclosing the door by means of screws (41), (42) .slidably therein. The block is provided with a rearwardly extending rod` (4A) which slidably engages the rear wall (4G) ofthe case while the spring (47) tends to `push the block forward so that its nose (48) engages the latch. The side of the block facing they frame is provided with a recess (49) containing a ball (51) which bears against the side of the case and facilitates the operation of the keeper. A pin (52) extends from the block (a2) outwardly through a, slot iny the caseA and allows the operator to pull ythe block rearwardly against the resistanceywhereby the samel is disof the spring (l')Y The block may be engaged from lthe latch.

held in this position bymeans of the meme ber (a) pivoted as shown at (56).

The operation of my device will be readily understood"y from the foregoing description;

To assemble the same itis only necessary to first insert the portion `(9)* of the plug from the inner end until its outer end is flush with theouter end of the 'housing inwhich place it may beheld by any suitable means as by the inturnededge (57) of the housing or the set screw (58)A engaging the annu-lar slot (59).

`Then the` portion ispushed' into the housing ani its cylindrical hole (26 is made to register with the hole (24) in the housing whereupon the latch (2Q) 'is screwed into the plug. T he housing may now be inserted in a suitable hole inthe door from the insidel and taken apart .very easily and may be se-V cured in any door without any ditliculty, the

only requirement on t-he part of the door being a: cylindrical hole through the same.:
